  Antiproliferative activity of Pt(IV)-bis(carboxylato) conjugates on malignant pleural mesothelioma cells

  摘要：

  The bifunctional Pt(IV) conjugate cis,cis,trans-diamminedichloridobis(valproato)platinum(IV), based on the cisplatin square-plane with two axial valproato (2-propylpentanoate, VPA) ligands, has been re-synthesized with a modified procedure and its biological activity was compared with that of its isomer cis,cis,trans-diamminedichloridobis(n-octanoato)platinum(IV). Both complexes showed a striking cytotoxic effect (in the micro or sub-micromolar range) on various human carcinoma cell lines (namely ovarian, colon, breast and lung cancer), and, in particular, on cells derived from malignant pleural mesothelioma. This remarkable activity is due to the action of the cisplatin metabolite only, generated by the intracellular Pt(IV)-> Pt(II) reduction, which concentration is greatly increased by the enhanced cellular accumulation of the original, highly lipophilic Pt(IV)-bis(carboxylato) complexes. The two axial VPA ligands are released in a too low concentration to act as histone deacetylase inhibitor (HDACI), as VPA works in the millimolar range, so that no synergism can be claimed. Moreover, n-octanoic acid is substantially deprived of any HDACI propensity. (C) 2013 Elsevier Inc. All rights reserved.

  biological properties of a Pt(IV) complex containing the very active inhibitor of histone deacetylase (2-propynyl)octanoic acid, POA, as an axial ligand are reported here. The title complex, namely (OC-6-44)-acetatodiamminedichlorido(2-(2-propynyl)octanoato)platinum(IV), 1, containing POA in racemic or in enantiomeric forms, was one/two orders of magnitude more active than cisplatin, depending on the chemo-sensitivity
